The number of anti-gay attacks in Russia is on the rise. Those speaking out for gay rights are being routinely beaten as police look on - sometimes by the police themselves. Now Russia's leaders claim a new law is not targeting gays. But people around the world find it so discriminatory, there is talk of boycotting the 2014 Olympic Games in Sochi. CNN's Phil Black has the latest from Moscow.

Greg Louganis suffered through two Olympic boycotts during his career as an Olympic diver. There is talk of a new boycott over a law targeting gays in Russia. But Louganis explains to Anderson why he does not want to see that happen during the 2014 Winter Games in Sochi and what he does want to see instead.

Anderson Cooper spoke with Senator John McCain about the ongoing humanitarian crisis in Syria two years after civilian protests began, leading to a brutal crackdown by President Bashar al-Assad and a violent conflict between government forces and the opposition.

They also discussed the issue of same-sex marriage in light of Republican Senator Rob Portman's announcement that he now supports gay marriage because his 21-year-old son is gay. McCain says he respect's Portman's decision, but disagrees because of his religious beliefs.

In an exclusive interview with CNN's Dana Bash, Ohio Senator Rob Portman announced he has changed his stance on same-sex marriage because his 21-year-old son is gay. CNN asked his conservative colleagues at CPAC to react to his reversal on the issue.
